I recently got the Oregon 450T. My main purpose is to mark my hunting and fishing spots. I recently purchased a new piece of land and have the NAD 83/91 coordinates for the corners. I am trying to see how I might get those converted to points I can put in my GPS so I can walk and mark the boundaries of my land. Anyone out there have any idea how I can do this? Or how I can use the points I have in my GPS? I have been unsuccessful in trying to do this so far. Thanks for any help.
